HOG-OILING APPARATUS. f

To all whom it may concern:

Be it known thatrI, PAUL P. LARKIN, a citizen of the United States, residing at South Charleston, in the county of Clark and State of Chio, have invented new and useful Improvements in I-IogOiling Apparatus, of which the following is a specication.

The object of my present invention is the provision of a simple, inexpensive and reliable 'hog oiling apparatus that is economical in operation inthe respect that while it is controlled by the movement of a hog between the gates it is not liable to waste oil in the event of the hog hesitating or stopping before it is clear of the gates.

The invention also seeks the provision of a hog oiler that is entirely automatic as well as economical in operation, and is efficient in oiling hogs ofvarious sizes.

lTothe attainment of the foregoing the invention consists in the "improvement as hereinafter described and definitely claimed.

In the accompanying drawings, hereby made a part hereof Figure 1 is a front elevation ofthe apparatus constituting the best aractieal emodiment of my invention that have as yet devised.

Fig. 2 is a plan view of the same.

Fig. 3 is an enlarged detail horizontal section showing the relative arrangement of the oil discharge spouts in the oil receptacle.

Fig. 4 is a section taken in the plane indicated by the line 4-4 of Fig. 3.

Similar numerals of reference designate corresponding parts in all of the views of the drawings.

The main frame of my oiling apparatus may be of any appropriate construction without involving departure from the scope of the invention as claimed.

I prefer, however, to have the main frame comprise horizontal parallel brace bars 1, and an open, rectangular sub-frame 2, fixed to and rising from the base bar 1.

Connected by spring hinges 3 to the side uprights of the sub-frame 2 are swinging doors 4, the spring hinges being of the type to permit the doors to swing in either direction, and being adapted to return the doors 4 and yieldingly maintain the same in the same vertical plane as the sub frame 2. Fixed to the hinged edge of one of the doors in an upright shaft 5 on which is fixed a miter gear 6. The said miter gear 6 is in- Specication of Letters Patent. Patented June 14- 1921.

termeshed with a miter gear 7, fixed on a transverse shaft 8 that is journaled in suit@ able bearings onthe side uprights of the Vsub-frame 2. Byy the said shaft 8 is carried an oil bowl 9 between which and an oil reservoir 10 superimposed on the sub-frame is disposed a supply conduit 12. The oil loowl 9 is equipped as best` shown in Figs. 3 and 4 with oil discharge pipes 18. In the preferred arrangement the said pipes 13 are provided with spout portions 14 arranged exteriorly of the` bowl 9. It will also be observed that the pipes 13 are' arranged substantially as shown relatively to the bowl 9 so that the pipes will always be covered with oil, and the spoutportions 14 of the pipes are preferably extended upwardly, Fig. 4, so that oil will not be discharged from either spout until the bowl 9 is tipped or canted. It will also be noticed that each of the pipes 13 extends from its spout portion 14 to a f .point adjacent 4to the opposite side of the bowl and as the bowl is tipped the inner end of the lowermost spout 14 is raised out of the oil, with the result that the oil discharged on the hogs back is the quantity of oil previously contained in the said pipe. By virtue of this arrangement a small amount of oil is deposited on the back of each hog as it passes through between the gates 4, and danger of wasting the oil in the event of the gates being held open is obviated.

In the practical operation of the appa-ratus it will be noted that as a hog passes between and swings the gates, the shaft 8 will be turned about its axis with the result that a small portion of oil will be discharged upon the hogs back. After the hog passes out of engagement with the gates the spring hinges will restore the gates to their normal position and will also return the bowl 9 to its normal position.

The reservoir 1() is a closed receptacle, and the lower end of the conduit 12 is normally immersed in oil in the bowl 9. Manifestly as the level of the oil in the bowl 9 rises the supply of air to the reservoir 10 will be cut off and hence the flow of oil from reservoir 10 to lbowl 9 will be stopped. lVhen the oil level in bowl 9 falls below the lower end of conduit 12, oil will pass from the reservoir 10 to the bowl 9 until the lower end of the conduit 12 is again sealed when the passage of oil will cease. In this way waste is prevented, and it is only incumbent on an attendant to keep the reservoir 10 charged with oil. A portion of the conduit l2 is shown as a flexible hose in Fig. 1.

Having described my invention, what I claim and desire to secure by Letters-Patent, is

1. The combination in a hog oiling apparatus, of a frame, a tiltable oil container having at the opposite sides thereof exterior oil spouts and also having interior pipes each of which extends 'from one spout to a point adjacent to the opposite side of the container and is disposed at an intermediate point in the height of the container, and means operable by the passage of a hog in either direction under the container to tilt the container and thereby discharge oil therefrom co-incident with the passage of the hog.

2. A hog oiling apparatus comprising a frame, a horizontally swinging gate, a vertically tiltable oil container, means to return the gate to and yieldingly maintain the same in a closed position, and means intermediate of the gate and the container to tilt the latter vertically by horizontal swinging movement of the former.

3. The combination in a hog oiling apparatus, of a frame, an oil reservoir superimposed thereon and having a discharge pipe7 a swinging gate mounted in the `frame, spring means to return the gate to and yieldngly maintain the same in a closed position, a shaft fixed to the inner edge portion of one gate and having a miter gear, a shaft journaled in the frame and having a miter gear intermeshed with the rst-named gear, and a container carried and adapted to be tilted by said shaft and having opposite discharge sprouts and also having interior pipes connected to said spouts and each extending from its spout to a point, adjacent to the opposite side of the container.

4:. The combination in a hog oiling apparatus, of a frame, a horizontally swinging gate, a vertically tiltable overhead oil container, and gearing connecting the gate and the container to tilt the latter, vertically by horizontally swinging movement of the former.

5. The combination in a hog oiling apparatus, of a closed reservoir, a vertically tiltable bowl, a supply pipe leading downwardly from the reservoir into the bowl and arranged to be sealed by oil in the bowl and means to tilt the bowl vertically incident to passage of a hog. under the bowl; the bowl being provided with a spout open at both ends and extending through one wall of the bowl and from a point adjacent to the opposite wall of the bowl.

In testimony whereof I aiix my signature.
